Most of the good ones have been mentioned already.
I agree with PTC,Neal Chance,and continental as very good choices.
Also would consider ATI,and coan at times as well.
For budget "street/strip" stuff,I would look into a redneck,hughes,or possibly a BTE converter or such.
I always avoid TCI,B&M,and such "high volume" brands as SOP.
